Question

escreva os logaritmos De N na base 10 para os casos a seguir

a) N= 100
b) N=√10
c) N=0.001
d) N=1

Answer 1

a) log ₁₀ 100 = x
10ˣ = 100
10ˣ = 10²
x = 2

b) log ₁₀ √10 = x
10ˣ = √10
10ˣ =  10 ¹/²
x = 1/2

c) log ₁₀ 0.001 = x
10ˣ = 0.001
10ˣ = 1/1000
10ˣ = 1/10³
10ˣ = 10 ⁻³
x = -3

d) log ₁₀ 1 = x
10ˣ = 1
10ˣ = 10⁰
x = 0
